UC Berkeley SafeTREC is excited to release the California Speeding and Aggressive Driving Study 2019 led by Ewald & Wasserman Research Consultants (E&W). This study was conducted on behalf of the California Highway Patrol (CHP) and the Safe Transportation Research and Education Center (SafeTREC) at the University of California, Berkeley.
The 2019 Survey
The Speeding and Aggressive Driving Study 2019 report describes the analysis results of the second wave of a statewide California Public Opinion Survey on driver perceptions on speeding and aggressive driving on California roadways. The first wave of the Speeding and Aggressive Driving Study was implemented in 2015 and repeated with an updated sample frame for the 2019 wave.
The study's objective was the surveying of a cross-sectional representative sample of California drivers and their perceptions and behaviors related to speeding and aggressive driving. Using in-person surveys at selected gas stations with an electronic data collection tool resulted in 1,526 completed intercept surveys in 21 selected counties and 67 site locations throughout the State of California. Survey data was collected from randomly selected California adult drivers in English or Spanish during the months of July and August, 2019. Read the full survey here.
